Sources told KSNV the gunmen ran into the the Cici's armed with rifles and bullet-proof vests at 11.27 a.m.

The pair then shot the officers - one in the head - and then took their firearms and ammunition before fleeing to a nearby Walmart while repeatedly shouting about a revolution beginning, police said.

One of the cops died at the scene as the other was rushed to a nearby hospital and was pronounced dead while in emergency surgery, according to the Las Vegas Review-Journal.

The two suspects shot then shot dead a a civilian who is believed to have been carrying a concealed firearm and had opened fire on them as they ran into the Walmart, Deputy Sheriff Kevin McMahill said during an afternoon press conference.

There were 'literally a thousand' witnesses to the terrifying events, Mc Mahill added.
